1982

1984

PostScript is older than the Macintosh. John Warnock and Charles Geschke founded Adobe in 1982 specifically to commercialize PostScript — a page-description language they had prototyped at Xerox PARC. The first public release came in 1984 when Apple licensed PostScript for the Apple LaserWriter, the $6,995 laser printer that essentially invented desktop publishing.

A .ps file is a complete PostScript program — code that instructs a printer (or a rendering engine like Ghostscript) how to draw each page. It is Turing-complete, which is both wonderful and terrifying: elegant procedural drawings are possible, and so are infinite loops, crashes, and security exploits. EPS is the sanitized, one-page, non-interactive subset. PDF is PostScript’s sandboxed descendant. Raw .ps files still appear in UNIX print pipelines and academic paper archives but are largely historical.

MERAK EDİLENLER VE
İLGİNÇ BİLGİLER.

Adobe was founded in 1982 specifically to commercialize PostScript — the company existed because of this format.

PostScript is a full programming language: Turing-complete, stack-based, similar to Forth.

Every laser printer from 1984 through the early 2000s was a PostScript interpreter running on dedicated hardware.

Apple's LaserWriter (1985) — $6,995, 512 KB of RAM dedicated to running PostScript — essentially invented desktop publishing.

Raw PostScript files can print and never halt — Ghostscript has a timeout to protect printers from infinite-loop programs.

GÜÇLÜ YÖNLER VE
SINIRLAMALAR.

Güçlü Yönler

Device-independent — same file prints identically on any PostScript printer.
Vector-based at heart; rasterization happens at the printer's DPI.
Programmable — dynamic pages, variable data, and procedural art all possible.
Legacy standard in academic and print pipelines.

Sınırlamalar

Turing-complete = security hole; malicious PS files can hang printers or exploit vulnerabilities.
Not a display format; browsers cannot render PostScript without conversion.
Mostly superseded by PDF (which is PostScript's sandboxed, declarative descendant).
File sizes can be enormous when embedding high-res images or fonts.
Modern Illustrator (2020+) deprecated PostScript import for security.
